P-15 Peptide Side Effects: Safety Signals and Warnings
P-15 Peptide safety concerns are compound-specific. The main listed side effects are Local swelling at surgical site, Potential allergic reaction to bovine-derived components, and Infection risk inherent to surgical procedures. The main warning signals are For surgical use only by trained practitioners, Contains bovine-derived material; contraindicated in patients with bovine protein allergy, and Not a substitute for mechanical stabilization in spinal fusion.
Direct Answer
P-15 Peptide (Puros) has Phase 2 data supporting its use as a bone graft substitute scaffold in dental and spinal surgery, with reasonable evidence for bone regeneration when used as a collagen/P-15 composite. It is a niche compound with a specific surgical application rather than a broadly applicable healing peptide. Within its bone regeneration niche, the Phase 2 data is credible.

Reported Side Effects
- Local swelling at surgical site
- Potential allergic reaction to bovine-derived components
- Infection risk inherent to surgical procedures
- Rare graft migration
Warnings
- For surgical use only by trained practitioners
- Contains bovine-derived material; contraindicated in patients with bovine protein allergy
- Not a substitute for mechanical stabilization in spinal fusion
- Efficacy depends on proper surgical technique and patient healing capacity
Known or Plausible Interactions
- Bone morphogenetic proteins (may have additive or complementary effects)
- NSAIDs (may impair bone healing and reduce P-15 efficacy)
- Bisphosphonates (may affect bone remodeling dynamics)
Regulatory Context
ABM/P-15 (i-FACTOR) received FDA 510(k) clearance for use in spinal fusion. PepGen P-15 has been used in dental applications. Available as a medical device/bone graft substitute. Requires surgical application by licensed practitioners.
